Abstract:

A new and distinct floribunda type Rosa hybrid named `GRAsuper` is
disclosed, characterized by complete resistance to Diplocarpon rosae and
continuous flowering. Plants produce pink flowers with a strong fragrance
and typically reach a height of between 1 to 1.2 meters. The new cultivar
is a Rosa typically suited for ornamental container and landscape use.

Claims:

1. A new and distinct cultivar of Rosa hybrid plant named `GRAsuper` as
herein illustrated and described.

Description:

LATIN NAME OF THE GENUS AND SPECIES

[0001] Rosa hybrid

VARIETY DENOMINATION

[0002] `GRAsuper`

BACKGROUND OF THE INVENTION

[0003] The new cultivar is the result of a chance discovery in a
commercial nursery in Highfields, Queensland, Australia. The inventors,
John Gray and Sylvia Gray, citizens of Australia, discovered the new
variety as a single whole plant mutation of the parent variety, a
floribunda type Rosa hybrid, `CHEWfragbabe`, unpatented in the United
States. The discovery was made October, 2009.

[0004] After selecting the new cultivar, asexual reproduction of
`GRAsuper` was first performed in the same commercial nursery by
vegetative cuttings March 2010. `GRAsuper` has since produced two
generations and has shown that the unique features of this cultivar are
stable and reproduced true to type.

SUMMARY OF THE INVENTION

[0005] The cultivar `GRAsuper` has not been observed under all possible
environmental conditions. The phenotype may vary somewhat with variations
in environment such as temperature, day length, and light intensity,
without, however, any variance in genotype.

[0006] The following traits have been repeatedly observed and are
determined to be the unique characteristics of `GRAsuper`. These
characteristics in combination distinguish `GRAsuper` as a new and
distinct Rosa hybrid cultivar:

[0007] 1. Complete resistance to the fungus Diplocarpon rosae.

[0008] 2. Repeat flowering.

[0009] 3. Plant height between 1 to 1.2 meters.

[0010] 4. Strong fragrance.

[0011] 5. Pink flower color.

PARENTAL COMPARISON

[0012] Plants of the new cultivar `GRAsuper` are similar to the parent,
Rosa hybrid `CHEWfragbabe` in most horticultural characteristics.
However, `GRAsuper` differs in flower color. Flowers of the parent
variety are white with champagne colored centers, whereas plants of the
new variety produce pink flowers.

COMMERCIAL COMPARISON

[0013] Plants of the new cultivar `GRAsuper` can be compared to the
unpatented commercial variety Rosa hybrid `Iceberg`. `GRAsuper` differs
from `Iceberg` in its complete resistance to Diplocarpon rosae.
Additionally, `GRAsuper` has more petals per flower, and new foliage with
a blue-purple blush not found on `Iceberg`. The two varieties also differ
in flower color, and `GRAsuper` has a stronger scent than `Iceberg`.

[0014] Plants of the new cultivar `GRAsuper` can be compared to the
commercial variety Rosa hybrid `MEIbeausai`, U.S. Plant Pat. No. 7,667.
`GRAsuper` differs from `MEIbeausai` in its complete resistance to
Diplocarpon rosae. Additionally, `GRAsuper` has smaller new foliage, with
serrate margins and a distinctive blue-purple blush on the new foliage
not found on `MEIbeausai`. `GRAsuper` also has a stronger scent than
`MEIbeausai`.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0015] The accompanying photograph in FIG. 1 illustrates in full color a
typical flower of `GRAsuper` grown outdoors in Highfields Australia. FIG.
2 illustrates in full color a typical plant of `GRAsuper` grown outdoors
in Highfields Australia. The plant is approximately 12 months old. The
photograph was taken using conventional techniques and although colors
may appear different from actual colors due to light reflectance it is as
accurate as possible by conventional photographic techniques.
